Exceptional active/standby MPU switchover

Symptom

While the device is operating correctly, the active MPU reboots and the standby MPU becomes the new
active MPU.

Solution

To resolve the problem:
1. In probe view, use the display hardware internal util slot slot-num rbinfo 5 detail command to
display reboot records.
2. If the most recent record is slave-rob, the standby MPU became the new active MPU because it did
not receive the heartbeat from the original active MPU. Wait for the original active MPU to start up
and troubleshoot IPC problems as described in the IPC troubleshooting guide.
3. If no slave-rob record is found, an exception occurred on the original active MPU.
If the system has entered kdb, contact HP Support.
